I have updated my PIC development environment described at
http://www.embedinc.com/pic.

The way it was (or mostly wasn't) dealing with initialization of passive
pullups had been bugging me for a while.  There used to be switch called
PORTBPULLUPS that you could set to TRUE or FALSE.  That's OK for the older
16 family PICs, but doesn't fit well with most of the new chips that have
individual pullup enables, and aren't limited to port B.

The /INBIT preprocessor directive now has a PUP option to indicate the
passive pullup on this pin is supposed to be enabled by default.  See the
PREPIC documentation file for details.  The assembler logic in the
template PORT module (QQQ_PORT.ASPIC) has been enhanced to check for
illegal combinations of pullups requested.  For example on an old PIC like
a 16F877, either all or none of the port B input pins must have pullups
enabled.  In that case you will get an assembly time error if both RB0 and
RB1 are inputs, but only RB0 has its pullup enabled.

The /INBIT and /OUTBIT directives now also create symbols to support the
LATx registers associated with each port of 18 family PICs.

There were probably other minor enhancements and fixes made to various
files that I don't remember now.
